Tensionning the drive chain (fig.10)
The drive chains need no tensionning since the tension is always assured by an idle
chain spanner.
To change the drive chain, pull the chain spanner backwards and remove the chain
from the sprockets and remove the chains.
After the chain is replaced always assure the chain spanner is well placed onto the
chain.
To change the drive chain for the rise and fall of the table, pull the chain spanner lever
to the back and remove the chain.
Attention: do not turn the sprockets on one of the 4 posts of the table whilest
chainging the chain; this will lead into a disorder of the parallelism of the table!
Problems and troubleshooting
1. The machine does not start when the start button is activated :
- workshop main fuse is switched off: power cut, power shortage, or general overload.
- main switch off: put switch on “1”.
2. Reduction of cutting speed when working :
- belt tension not correct: tension the belt
- motor overload due to incorrect feed rate: reduce the feed rate
- blunt tools: sharpen tools
3. Vibration of the machine :
- worn or damaged belt: replace the belt
- overtensionned belt: loosen belt
4. Thermal overload does not re-arm automatically after shut-off and cooling down
period :
- overload is not set on automatic reset, or the overload is faulty: set on automatic, or
replace
